| Saksham | Re: IIT JEE question papers free download You are searching for the IIT JEE Part I: Chemistry question papers. Here I am providing you the IIT JEE Part I: Chemistry some sample question. That is as follows. The Henry’s law constant for the solubility of N2 gas in water at 298 K is 1.0 × 105 atm. The mole fraction of N2 in air is 0.8. The number of moles of N2 from air dissolved in 10 moles of water at 298 K and 5 atm pressure is (A) 4.0 × 10−4 (B) 4.0 × 10−5 (C) 5.0 × 10−4 (D) 4.0 × 10−6 Sol. (A) P = KH 2 N χ 0.8 × 5 = 1 × 105 × 2 N χ 2 N χ = 4 × 10-5 (in 10 moles of water) 2 2 N 5 N n 4 10 n 10 − ⇒ × = + 2 2 5 4 N N n 5 10 4 10 n − − × × + × = 2 4 Nn 4 10− ⇒ = × Here I am also uploading a file that contains the IIT JEE Part I: Chemistry question detail papers.
